[SCRIPT] Can't pick up my custom item

[Amce]

Hi, i've made a custom item, a type of key to be exact, and it works nicely ingame, I can see it glowing blue lying there on the ground.
However, when i click it, nothing happens. I can't pick it up. Has anyone had the same problem and how did you solve it?


Also, I searched for but couldnt find, a way to make an item unable to be picked up, for example a key lying by the fire, so that when u try to pick it up it says something like, "The Key is too hot to pickup!". But after some random event a func should be activated to enable the key to be picked up. I hope you understand! thanks!
